This application is a continuation of U.S. patent application Ser. No.15/220,235, filed Jul. 26, 2016 which is hereby incorporated byreference in its entirety.

BACKGROUND

In a typical prior-art quality test system for end-user devices such asset top boxes and game consoles, multiple units under test (UUT) arecoupled to multiple media-test boards. The media-format boards (MFTs)may each offer a set of media format conversion functionality. Theconnectivity employed between a particular UUT and its associated MFBmay vary according to the make and model of the UUT and or MFB. SomeUTTs may receive signals which are not directed from or through the MFBwith which they are associated, for example signals from a serviceprovider head-end. The inputs to a MFB, UUT, and the connections betweenan MFB and UUT, may vary according to the make and model of UUT,complicating the testing process.

Polling, control, initialization, and configuration signals aretypically provided by the service provider (e.g., a cable televisionnetwork operator, an Internet Service Provider, etc.) to the UUT and aresupplied via a direct connection between the UUT and the serviceprovider network. In order to swap a UUT with another for testingpurposes, it may be necessary to manually reconfigure the connectionsbetween the UUT and the MFB, and the UUT and the service provider.

Each MFB may be coupled to test logic (e.g. a laptop computer), forexample via a Universal Serial Bus (USB). Each MFB may drive an infrared(IR) signal source to control the UUT. A USB hub may be employed toexpand the number of ports available on a laptop, personal computer, orother test device.

These conventional test system tend to suffer from poor performance andlack of scalability.

BRIEF SUMMARY

Disclosed herein are a machine architecture implementing a stagingautomation process, including features such as multiple IR transmittersand composite video inputs for automated high volume quality testing.Diagnostic display outputs from a unit under test are input to OCR andvideo quality algorithms to validate that the units under test are readyfor a functional test process at the next stage. Units under test havingDOCSIS capability (DSG) are manipulated using, for example, an SNMPprotocol, replacing OCR. Communication is carried out through a DSGchannel from a main controller to the unit under test for diagnosticinformation retrieval and request of command execution by the unit undertest.

DETAILED DESCRIPTION

Systems and processes are described herein to execute verifications ofunits under test (e.g., set top boxes) prior to provisioning of theunits under test by a headend controller. Verifications may include oneor more of power detection, boot detection, RF out of band (00B) healthstatus, and a conditional access security check. One or more of theseverifications (e.g., the conditional access security check) may varyaccording to the manufacturer of the unit under test (e.g., Motorola andPace use Unit Address, Cisco uses MAC).

Units under test (UUT) that do not pass the verifications are suppressedfrom proceeding to an initialization and code download stage(provisioning) from a headend main controller. A result is reducedlatency time for provisioning the UUTs that pass verification.

The system utilizes concurrent processing in a temporal overlap intervalto detect intermittent failures exhibited during a UUT warm-up phaseand/or pre-provisioning phase that overlaps with a provisioning phasewithin a set of UUTs. Examples of warm-up phase failures that may bedetected are unit reboots, video tiling, in band (IB) tuner correctedand uncorrected byte and/or block increases, and loss of provisioningstability.

Disclosed herein are embodiments of an analytic system for testing alarge number of units under test (UUTs). The analytic system includes arack system having multiple testing units (sometimes referred to hereinas video hardware units) and UUTs. Each of the testing units receivesvideo inputs from a corresponding different subset of the UUTs andoutputs infra-red commands to the corresponding different subset of theUUTs to drive quality testing of the UUTs. Each of the testing unitsexecutes in parallel a pre-provisioning phase, a provisioning phase, anda post-provisioning phase on subsets of the UUTs, and reconfigures theinfra-red commands to the UUTs and the video inputs from the UUTs inresponse to results of the pre-provisioning and provisioning phases.

Each of the testing units receives via the rack system a UUT test from amaster control remote from the rack system (e.g., a web server system).Each of the testing units returns via the rack system UUT test resultsto the master control. The master control interoperates with a cablesystem headend to communicate the UUT test and to receive the UUT testresult via a web server system.

The testing units may operate the provisioning phase on a first subsetof the UUTs in parallel with operating the post-provisioning phase on asecond subset of the UUTs. In one embodiment, the testing units eachinclude video processors each configured to receive at least tenindividual composite video inputs, and the testing units are eachcoupled to an infra-red driver board with at least ten individualinfra-red outputs. The infra-red driver board may also control a towerlamp for the rack system.

The rack system distributes radio frequency video from the cable systemheadend to each of the UUTs via a master RF splitter coupled to aplurality of domain-level RF splitters on different levels of the racksystem. The master RF splitter may be controlled by a master video testunit that also coordinates testing of the UUTs among the various other(subservient) test units.

Referring to FIG. 1, a distributed quality test system 100 comprises amain controller 120 acting as a master control for a plurality of slavecontrollers, e.g. video hardware unit 112 and video hardware unit 114.The main controller 120 also controls a headend controller 126 to driveRF audio and video (AV) feeds to the set top boxes 108 and set top boxes110. The video hardware unit 112 and video hardware unit 114 controlgroups of UUTs, e.g. set top boxes 108 and set top boxes 110. Inresponse to infrared (IR) controls from the video hardware unit 112 andvideo hardware unit 114, the set top boxes 108 and set top boxes 110each drive composite video (CV) to the video hardware unit 112 and videohardware unit 114, respectively.

The main controller 120 interacts with the video hardware unit 112 andthe video hardware unit 114 through a subsystem that includes a VPNgateway 116 and a VLAN 118. The main controller 120 communicates UUTtest 122 to the video hardware unit 112 and to the video hardware unit114, and the UUT test 122 receives test results 124 from the videohardware unit 112 and the video hardware unit 114. The main controller120 interacts with the headend controller 126 through a subsystem thatincludes a VPN gateway 102, a router 104, and a VLAN 106.

In one embodiment the main controller 120 is implemented as a Djangoframework. The main controller 120 configures and stores one or more UUTtest 122. The UUT test 122 may be one or more sets of sequentialoperational tests each for a specific UUT type or a test framework for aUUT family. The main controller 120 may operate as a message broker thatcommunicates the UUT test 122 to the video hardware unit 112 and thevideo hardware unit 114. The main controller 120 may also monitor thestate of operation of the video hardware unit 112 and the video hardwareunit 114, for example by applying controls requesting the current statusof ongoing tests. The main controller 120 may also poll to determine thepresence of the test results 124 at a predetermined location, forexample, in a shared file system folder of the server test system 404.

The current status of ongoing tests by the video hardware unit 112 andvideo hardware unit 114 on the set top boxes 108 and the set top boxes110 may be displayed in a web graphical user interface by the maincontroller 120. The main controller 120 may also control a tower lamp506 to inform human operators of the status of the tests on the UUT's inthe quality test rack 500.

The main controller 120 may communicate with the video hardware unit 112and video hardware unit 114 using HTTP packets. Each packet may comprisea single command that complies with a predefined schema and format.

Referring to FIG. 3, a test system 300 includes a quality test rack 500coupled to a headend controller 126 and many set top boxes. One set topbox (set top box 312) is illustrated, but many dozens (e.g., 40 or so)may be tested simultaneously by the test system 300.

The quality test rack 500 comprises a main video hardware unit 304, anRF switch 306, and many RF splitters 308.

A human operator may install the units under test on the quality testrack 500 (e.g., up to 40), connect cables (e.g., power cables, RF inputcables, and composite video cables). The human operator may also scanbar codes labels on the unit under test (e.g., for a particular productcode) before initiating a pre-provisioning verification processingstage.

Referring to FIG. 4, a distributed quality test system 400 includes aserver test system 404 and a video hardware unit 410 that interoperatewith one another over the Internet 402. More particularly, an embeddedtest module 408 of the video hardware unit 410 interoperates with a maincontroller 120 of the server test system 404. The main controller 120may comprise a web application and web user interface.

The server test system 404 communicates a UUT test 122 to the embeddedtest module 408. The embedded test module 408 applies the UUT test 122to analyze composite video 418 received from multiple units under test,and to operate an IR blaster 416 to operate the units under test.Results of applying the UUT test 122 are communicated by the embeddedtest module 408 to the main controller 120.

By way of example, the main controller 120 may be implemented using anApache web server with a web user interface to display status andresults encoded by the test results 124. The UUT test 122 and testresults 124 may be XML files or direct controls exchanged using TCP/IPsockets.

Referring to FIG. 10, a distributed quality test system 100 includesvarious components that interoperate with one another using a mastercontroller 1022, which may in one embodiment be implemented as an FPGA(Field Programmable Gate Array). The audio/video processing device 1000may comprise additional components which are not shown as they would bereadily understood to be included or optionally included by those ofrelevant skill in the art.

The distributed quality test system 100 includes a processor 1002 (e.g.,a general purpose data processor), a video processor 1014, and a videoprocessor 1016. Although two video processors are illustrated, otherembodiments of the audio/video processing device 1000 may utilize morethan two video processors.

The video processor 1014 and the video processor 1016 each operate an RFtuner 1028 to extract selected RF channels from an input RF broadbandsignal (e.g., comprising multiple QAM channels). A baseband audioprocessor 1026 extracts audio for the selected RF channels. The videoprocessor 1014 and the video processor 1016 operate on video from the RFchannels, and an audio processor 1024 operates on the audio from the RFchannels. The video processor 1014 and video processor 1016 also operateon a plurality of composite video inputs 1032 and composite video inputs1034 from the UUTs in the quality test rack 500.

An additional input of HDMI audio and video to the audio/videoprocessing device 1000 may be provided via the HDMI input controller1020.

In coordination with the master controller 1022, the processor 1002executes the UUT test 122 received from the server test system 404 andoperates various components of the audio/video processing device 1000 totest a plurality of UUTs in the quality test rack 500. Componentsoperated by the processor 1002 to execute and report results of the UUTtest 122 include IR output controller 1018, Ethernet I/O controller1012, USB I/O controller 1010, RF tuner 1028, video processor 1014,video processor 1016, and audio processor 1024.

The IR output controller 1018 may interoperate with the other systemcomponents via the master controller 1022 using, for example, an SPIserial interface, The IR output controller 1018 may output IR controlsignals to the UUTs in the quality test rack 500 in both serialized andparallel output modes of operation. The IR output controller 1018 mayalso be operable to control the tower lamp 506.

The HDMI input controller 1020 may interface and interoperate with themaster controller 1022 via a serial I2C interface. The HDMI inputcontroller 1020 may operate in combination with internal or externalexternal HDMI switch controller 1008 to process HDMI inputs from theUUTs installed on the quality test rack 500. The input HDMI maysupplement or replace the composite video inputs 1032 and compositevideo inputs 1034 for purposes of executing the UUT test 122. The RFtuner 1028 and baseband audio processor 1026 may be operated incoordinated fashion to select RF channels from the UUTs for testing. TheRF tuner 1028 may interface via an I2C interface and may utilize an RFswitch (not illustrated) to select RF inputs from the UUTs. The RF tuner1028 inputs may supplement or replace the composite video inputs 1032,composite video inputs 1034, and/or HDMI inputs when executing the UUTtest 122.

Execution of the UUT test 122 by the audio/video processing device 1000produces the test results 124 that are communicated to the server testsystem 404 via one or more of the USB I/O controller 1010 or EthernetI/O controller 1012.

Referring to FIG. 11, a quality test process 1100 is started and a maincontroller initializes and starts up an operator interface (block 1102).The operator installs a batch of set top boxes on a rack test system(block 1104). The operator scans the serial unit address bar codes ofall the set top boxes (block 1106) and initiates execution of parallelbatch testing of the set top boxes (block 1108).

The main controller downloads to the XML test files to the slavecontrollers on the rack and the slave controllers carry out the tests onthe set top boxes. The main controller polls for results of these tests,e.g. in a predetermined file system directory or directly to the slavecontrollers. See block 1110.

The main controller continually updates a web GUI with test results fromthe slave controllers (block 1112), and eventually the batch testingcompletes (block 1114) and the operator unloads the set top boxes fromthe rack (block 1116).

Referring to FIG. 12, a multi-unit test process 1200 starts and performsparallel pre-provision verifications of multiple UUTs (block 1202).Provisioning is suppressed for those UUTs that fail the pre-provisioningverifications (block 1204). UUTs that pass pre-provision verificationsare provisioned (block 1206). Post-provision tests are suppressed onUUTs that fail to provision (block 1208). Those that provisionsuccessfully are tested further (block 1210).

Referring to FIG. 13, a multi-unit test process 1300 starts and performsparallel pre-provision verifications of a first set of UUTs (block1302). Provisioning is suppressed for those UUTs that fail thepre-provisioning verifications (block 1304). UUTs that passpre-provision verifications are provisioned (block 1306). Post-provisiontests are suppressed on UUTs that fail to provision (block 1308). Thosethat provision successfully are tested further (block 1310).

The multi-unit test process 1300 performs parallel pre-provisionverifications of a second set of UUTs (block 1312) during theprovisioning of UUTs in the first set that pass pre-provisionverifications (block 1306). Provisioning is suppressed for those UUTs ofthe second set that fail the pre-provisioning verifications (block1314). At block 1316 UUTs of the second set that pass pre-provisionverifications are provisioned in parallel with testing the UUTs from thefirst set that successfully provision (block 1310). The testing of theUUTs in the second set then proceeds as for the testing of the UUTs inthe first set. Parallel testing of UUTs in a third set may then commencein parallel with testing of the UUTs in the first set and UUTs in thesecond set, in like fashion.
